Thanks for the replies, Alan you are dead right this is a throttle position switch error, not as described by Autodiagnose as an engine speed error. You have helped me get a more accurate picture; thank you.

Gwyn thanks I have replaced the throttle pedal switch which is basically a magnet and adjusted it and wallah we have communication and no code. Thanks to all the suggestions and your help I just wish I could be more helpful with my knowledge at times. Thank you, Guys.
